What is it used for? Trivial question, but can it receive/transmit data from different transceivers? I mean, e.g. one master station receives data from other slave stations simultaneously.Not simultaneously in the literal sense but I think you can have several of these all talking to each other or a central device.Actually I would like to create a online data monitoring system to receive data from various places wirelessly. Over the project want to learn related things that can be useful.There are several tutorials on using these transceivers if you search...http://arduino-info.wikispaces.com/Nrf24L01-2.4GHz-HowTohttp://forum.arduino.cc/index.php?topic=138663.0http://maniacbug.wordpress.com/2011/11/02/getting-started-rf24/to name a few. I am newbie, so have a trouble understanding the use of this UART device.You probably don't need the extra bit that converts the wireless data to Serial (UART) so this will make it a bit cheaper. you only need this to send/receive radio signals. (I have no affiliation to the eBay site, it was just the first one I found.)
Could you also explain what STC15L204 used for? I mean as a UART device. I'm really curious about it. On the internet I didn't found someone that used this module.
